    Default Alpha 1 gen 1 questions

    I know this isn’t really a hot boat, but I had great luck in the jet section when I was brand new to boating...

    Just picked up a 89 sea ray sorrento 21 with 260 hp 5.7 and alpha 1 gen 1 drive. The boat has been well cared for, engine seems to be all in order, may change valve springs due to age, but I know next to nada about outdrives.

    Question is, assuming nothing has been replaced or serviced for the past 4 yrs, what should be replaced at this point?
    My list as of this point includes:
    Water pump impeller
    Anodes
    All 3 bellows
    U joints
    Drive oil (Lucas or quicksilver?)
    All seals in the drive?


    Lastly, I don’t have a great local source for marine parts, who is great to deal with and willing to spend a few min on the phone with a newbie customer?

    Boating is nothing like cocaine, boating is much more addictive and results in bigger parties!

    Anytime I have a stern drive off I check engine alignment. On top of your list since it will be apart to do bellows I would suggest replacing gimbal bearing and water hose.

    Can I check crank/flywheel alignment with an old “MR” drive input shaft or do I have to get my hands on a tool from a Mercruiser dealer?

    Default outdrive

    you can go to your local NAPA store with the serial and model numbers off of the drive and also you will need the engine model and serial numbers
    they can get you a complete kit with everything you will need. USE ONLY MERC DRIVE GEAR LUBE. I use to work as a marine mechanic. did a lot of merc outdrives

    I did the same thing. I have owned 8 V-drive flatbottoms since the '70s. Most were race boats. My wife said it is time for a BFB. Big Family Boat. So I went out and bought a 1988 Wellcraft. 454 Bravo One. It was running when I picked it up. I let is sit for the winter. Then I took it to a highly recommended shop. I told him I knew nothing about outdrives and Mercruisers. I wanted it gone through from trailer to dashboard. I made an appointment and he told me what ever I do, don't even turn over the engine without water. OK. He did the most detailed inspection I have ever seen. Many things are in need of replacement or repair. Hoses, motor mount, battery, etc. etc. etc. I will probably have $2,400 in service and repairs. But hey, I am semi retired now and plan on spending much of the Spring, Summer, and Fall on the water with a boat that will hold many people instead of just 1 or 2 seats.

    This is a picture of the same boat I bought. Even the color.

    Thank you guys, the local Napa store got me a Sierra kit.

    For anyone else just starting in the out drive world a gear lube pump is an absolute must. I can not imagine trying to fill this thing with just a squeeze bottle.

    I attempted to do the same thing but discovered that our only local boat/marine shop is owned by a complete idiot. He didn’t stock any quicksilver products, tried repeatedly to sell me an alpha gen 2 water pump kit insisting it would work on a gen 1, and was re decking a pontoon with plywood straight out of Home Depot in the bay of the shop. I decided I was better off dealing with a Merc dealer 2 hours away, who also recommended the local Napa jobber.
